6.3.20 HVPS DB failure
NOTES:
1. The diagnostic tool is not used in this FIP. See Diagnostic Tool test DG93.
2. There is no corresponding control panel message
3. This FIP may also fix all blank page prints or a bad toner cartridge.
4. Try another Toner cartridge.
1. INITIAL ANALYSIS
Inspect the following components. Are they compatible with your printer version, correctly
installed, not damaged, deformed, or contaminated?
LVPS Assembly MCU PWB
HVPS Earth Plate Assembly
HVPS Harness Assembly
Yes No
Go to Step 2. Replace the problem components.
2. HVPS ANALYSIS
Is there +24VDC between P15–7 and P15–1 on the MCU PWB?
Yes No
Go to Step 3. Go to Section 6.3.2 LVPS Assembly Failure (+24VDC).
3. EARTH PLATE ASSEMBLY ANALYSIS
Unplug the AC power cord from the back of the printer.
Remove the Toner Cartridge.
Is there continuity (0
Ω)Ω)
between DB (Spring Plate) on the Earth Plate and J DB–2 on the
HVPS
Yes No
Go to Step 4. Replace the Earth Plate Assembly.
4. HVPS HARNESS ASSEMBLY ANALYSIS
Disconnect P/J111 on the HVPS and P/J15 on the MCU PWB.
Is there continuity (0Ω) Ω) between all wires on P/J15 on the MCU PWB and P/J111 on the
HVPS?
Yes No
Go to Step 5. Replace the HVPS Harness Assembly.
